Question posted in 
I’m following Apple’s Safari Web Content Guide – Configuring Web Applications and it works as expected most of the time. But when I want to add to favorites on iPhone, the favicon doesn’t show up. Is it the size issue? Or what else should I do for the favorites icon to show up? Thanks
My Code:
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="icon" type="image/x-icon/" href="{{ "/favicon.ico" | relative_url }}">
<link rel="apple-touch-icon" href="{{ "/apple-touch-icon.png" | relative_url }}">
<link rel="apple-touch-icon" sizes="76x76" href="{{ "/apple-touch-icon-76x76.png" | relative_url }}">
<link rel="apple-touch-icon" sizes="120x120" href="{{ "/apple-touch-icon-120x120.png" | relative_url }}">
<link rel="apple-touch-icon" sizes="152x152" href="{{ "/touch-icon-ipad.png" | relative_url }}">
<link rel="apple-touch-icon" sizes="180x180" href="{{ "/touch-icon-iphone-retina.png" | relative_url }}">
<link rel="apple-touch-icon" sizes="167x167" href="{{ "/touch-icon-ipad-retina.png" | relative_url }}">
{%- seo -%}
<link rel="stylesheet" href="{{ "/assets/main.css" | relative_url }}">
{%- feed_meta -%}
{%- if jekyll.environment == 'production' and site.google_analytics -%}
{%- include google-analytics.html -%}
{%- endif -%}
<!-- site css -->
<link rel="stylesheet" href="{{'/assets/main.css' | prepend: site.baseurl}}">
{% seo %}

I have figured it out and it is displaying the favicons properly now. Thanks a lot, @Charlie, for the favicon checker website: https://realfavicongenerator.net/favicon_checker#.YIHdji1h0Ts

Per Apple’s current guidance, default touch icon sizes are as follows:
